Abstract:
A hand-moving mechanism moves a hand and includes a stepping motor and a wheel train mechanism. The stepping motor includes a plurality of coils and rotates a rotational shaft thereof in forward and reverse directions. The wheel train mechanism includes a plurality of gears having: one gear which is coupled to the rotational shaft of the stepping motor; and another gear which is coupled to the hand. The stepping motor includes two coil cores which are arranged in a vicinity of a peripheral edge portion in a module having a bent peripheral edge portion, which have a linear shape respectively and which extend from a central coupling portion respectively. Each of the two coil cores is formed to be bent at a predetermined angle following a bent shape of the peripheral edge portion of the module, so as to sandwich the central coupling portion between the two coil cores.
